Summary: Spores of D mutants of prepared on a rich medium were defective in their germination responses to L-alanine, to a mixture of -asparagine, -glucose, -fructose and KC1 (AGFK), and to Penassay broth. They showed an increased response and sensitivity to L-alanine when monovalent cations were also present. When prepared by a resuspension method, the spores had an improved germination response to L-alanine, even in the absence of these cations, but showed no such improvement in response to AGFK. No gross differences were found between wild-type and spores in heat or chemical resistance, dipicolinic acid level or morphology. It is proposed that an alternative pathway of germination involving monovalent cations exists in both wild-type and spores.
